Frequent Questions

What does EPA registration of home water treatment units indicate?

EPA requires registration of certain filters in home water treatment units that incorporate a disinfectant to inhibit microbial growth.  This registration indicates that the manufacturer has shown that the pesticide will not cause adverse health effects when used as directed.  Registration does not indicate that EPA approves or endorses a home water treatment unit; any such claim that EPA approves or endorses home water treatment units is false (Home Water Treatment Units: Filtering Fact from Fiction, EPA570-9-90-HHH; September 1990).
